Abstract

1,238,943. Mixing apparatus; polymerisation apparatus. MITSUI TOATSU CHEMICALS Inc. 17 Sept., 1968, No. 44206/68. Headings B1C and B1X. [Also in Divisions C3, F3 and F4] In apparatus for treating viscous materials e.g. for polymerization, the temperature of the material is maintained at a substantially uniform level by continuously moving in paths 14, 15 in a vessel 11 having a heat exchange shell, a heat exchange tube 12 concentrically and spacedly mounted within the shell, as rotary screw 13 within the tube 12 and heat exchange tubes 17 mounted within the space between the tube 12 and shell. A series of such vessels may be linked with a gear pump 28 on the final vessel controlling the flow volume of the materials through the apparatus as a whole. A first stage reactor vessel has an agitator 7 with turbine-type vanes in two steps which are twisted to obtain reverse flows.
